DESCRIPTION
Ferrosilicon is an alloy of iron and silicon that is commonly used in the production of steel and other iron-based alloys. It is produced by reducing silica with coke in a furnace, along with iron, and can vary in silicon content from 15% to 90% by weight.
Ferrosilicon is used as a deoxidizer, an alloying agent, and as a source of silicon and iron in the steelmaking process. It can improve the mechanical properties of steel, including its strength, hardness, and ductility. It can also be used in the production of cast iron, as well as in the manufacturing of other alloys, such as aluminum-silicon and magnesium-silicon alloys.
Different grades of ferrosilicon are available, with varying silicon content and particle size, to meet specific application requirements. For example, a high-silicon ferrosilicon with a low carbon content may be used to produce stainless steel, while a low-silicon ferrosilicon with a higher carbon content may be used in the production of cast iron.
| Grade | Silicon Content (wt.%) | Aluminum Content (wt.%) | Carbon Content (wt.%) |

| FeSi 75 | 75 | 1.5 | 0.2 |
| FeSi 72 | 72 | 2.5 | 0.2 |
| FeSi 65 | 65 | 2.0 | 0.2 |
| FeSi 45 | 45 | 2.0 | 0.2 |
| FeSi 15 | 15 | 2.0 | 0.2 |
